Regardless of whatever happened today, it's never a good time to buy $DJT because 1) it's not profitable and 2) holders are slowly continually liquidating in a complicated manner explained by past Money Stuff articles.
The actual quote is "THIS IS A GREAT TIME TO BUY!!! DJT", which makes DJT either a signature and a call to buy the market if he can form a valid sentence, or a call to buy NASDAQ:DJT if he can't form a valid sentence. Take your pick. It's market manipulation either way.
Clearly some listened or simply had knowledge the announcement was coming.
